joberlee Posted March 2, 2005 Report Share Posted March 2, 2005 There is no MAF on a 3.1 mpfi, only on the 3.8 and early 2.8s Quote Link to comment Share on other sites More sharing options...

Robby1870 Posted March 2, 2005 Report Share Posted March 2, 2005 MAT/IAT Manifold intake Temperature/Intake Air Temperature. It just tells the ECM the temp of the air entering the engine. Quote Link to comment Share on other sites More sharing options...
Dannymik Posted March 2, 2005 Report Share Posted March 2, 2005 There is no MAF on a 3.1 mpfi, only on the 3.8 and early 2.8s not to take away from the topic, but isn't there one in on the 3.4 as well? Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted March 2, 2005 Report Share Posted March 2, 2005 yeah, the later DOHC's had them, like 95+ I think. Quote Link to comment Share on other sites More sharing options...
GP1138 Posted March 2, 2005 Report Share Posted March 2, 2005 yeah, the later DOHC's had them, like 95+ I think. Later 3100's had MAF as well. My Auto school has a Lumina ('98 I think) that has a MAF sensor. Quote Link to comment Share on other sites More sharing options...
bartonmd Posted March 3, 2005 Report Share Posted March 3, 2005 What you are descirbing is the same thing my buddy's euro did... It IS the torque convertor lockup solenoid... It basically feels like you are stopping in a stick without your foot on the clutch... engine bogs down, IAC tries to bring it back, hense, the jerking. Torque convertor solenoid is a $30 part that was redesigned in '91 so it doesn't do it as bad. It's actually a screen on the solenoid that gets clogged up and causes the TCC solenoid to stay engaged. He's a mechanic (Dodge), but has friends who work at the Pontiac/Olds place and they say those years of cars do this sometimes when that screen gets clogged. $35 and 2 hours. done.
